Mayde Gomez introduces us to Cool Kid Salvador Medina, who volunteers for the Union Rescue Mission, a homeless shelter in Los Angeles. Medina knows what it's like to be homeless; his family went through a rough time when he was just 8 years old. According to the Union Rescue Mission, there are about 47,000 homeless people in L.A. County. Salvador says treating those in need with respect is important. He hopes to go to college and one day start his own business, and that includes a lifelong commitment to giving back.
